IMPROVEMUENT t COCKS AN'D FAUCETS.

Specification forming part'of Letters Patent N0. 173,849, dated February 22,1876; application filed January 29, 1876.

To all whom it may concern:

Beit known that I, CHARLES K. DIGKSON, Jr.,of St. Louis,'in the county of St. Louis, and State of Missouri, have invented a new and useful Improvement in Indicating-and Operating Device for Three-Way Cooks, of which the following is a specification:

Figure l is a side view of my improved device shown as applied to a three-way cook, the

cock being shown in section. Fig. 2 is a View of the same turned one-quarter around.

. venient in use.

The invention consists in the combination of the'three-armed head with the plug of a three-way cock, in such a way that the said arms may be directly over the openings of said plug, to indicate the position of said openings with reference to the three pipes of the cock; and in the combination of the key, provided with a threearmed head on its low er end and a three-armed handle upon its upper end, with the three-armed head of the plug of a three-way cock, to indicate the position of the openings of the said plug with reference to the three pipes of the said cock, as hereinafter fully described.

A represents the body of the cock, which is made with three pipes, a e a set at right angles with each other, as shown in Fig. 3. The valve-seat of the cock A is made tapering or conical, in the usual way, and into it is fitted the tapering valve or plug B, which is secured in place by a nut and washer, in the usual way. In the plug B are formed three openings, 12 1) b corresponding with the three pipes 01. a a of the cock. The openings b b b are at right angles with each other, and meet in the center of the plug B. .The' inlet-openings a b should be larger than outlet-openings at a 1) b so as to furnish a full stream of water to the pipes leadingfrom I said outlet-openings.

To the upper part'of the plug B is attached a pen, I), which enters a notch, it, in the top of the cock A, and

which extends three-quarters around said top. By this construction the plug B can be inserted in only one way, and can only be turned through When the plug B is in the position shown in Figs. 1' and 3, all the openings are open. When the plug B is turned through one-quara ter of a revolution'th'e opening a is closed, leaving the openings a a open. When the plug B is turned through one-half a revolution the opening a is closed, leaving the openings afl'af open.- When the plug B is turned through three-quarters of a revolution the opening a? will be closed, which'entirely shuts ot't' thewater. Upon the stem of the plug B is formed a three-armed head, 0, the arms of which are at right angles with each other, and

are directly over the openings b b b so that the position of said arms with reference to the pipes au a indicates exactly in what position the openings of the plug B are with reference to the pipes a a 0. D is the key by which the plug B is turned, and in thelower end of which is formed athreearmed head, d, to fit upon the three-armed head of the plug B, as shown in Figs. 1 and 2. Upon to enable two hquses, or a house and a streetwasher, to be supplied with water by tapping the water-main once, and in such a way tha the water can be shut oft from either outletpipe without affecting the other, and to be shut off from both when desired.

Having thus described my invention, Iclaim as new. and desire to secure by Letters Pat- I ent 1. The combination of the three-armed head 0 with the plug B of a three-way cock, the said arms 0 being directly over the openings of said plug B, to indicate the position of three-quarters of a revolution."

said openings with reference to thethree pipes of the cooks, substantially as herein shown and described.

2. The combination of the key D, provided with a three-armed head, d, on its lower end, and a three-armed. head or handle, d upon its upper end, with the three-armed head of the plug B of a three-way cock, to indicate the position of the openings of the said plug with reference to the three pipes of the said cock, substantially as herein shown and described.
